Uncrewed Underwater Vehicles

MSubs’ Uncrewed Vehicles are designed to be affordable and easy to operate and maintain. Our UUV hull designs are based on our crewed submersibles, enabling most systems and components to be within the pressure hull. This enables MSubs UUV’s to be maintained and replenished without recovery, reducing turnaround time. Additionally, by utilising Submergence Group’s SUBNAVSYS integrated bridge system, MSubs’ larger UUVs can be operated either crewed or uncrewed.

MSubs is also the distributer of Martac Mantas hybrid and surface ASV’s. The range spans from the lightweight and readily portable to extreme-performance, large-payload, ocean-going vessels.

Vehicle transportation 3 x 40’ ISO containersThe Mobile Anti-Submarine Training Target (MASTT) Unmanned Underwater Vehicle (UUV) was built in response to the US Navy’s request for a rapid prototype, low cost UUV for Anti-Submarine Warfare (ASW) training. It also provides an optimum platform for conducting threat detection analysis training as well as countermeasure and torpedo system testing. The MASTT UUV is towed to the operation area and then released to execute the required mission profiles in support of tactical training evolutions.Length:

From outline specification to launch took just 14 months. Dived performance is maximised by attention to streamlining of the outer hull and by the use of advanced motor technology to directly drive the main propeller.Length:
